Answer:
B. 1.291%
Explanation:
The computation of the standard deviation is shown below;
= 2000 + 2001 + 2002 + 2003
= 0.5 × 14% + 0.5 × 16% + 0.5 × 15% + 0.5 × 17% + 0.5 × 16% + 0.5 × 18% + 0.5 × 17% + 0.5 × 19%
= 15% + 16% + 17% + 18%
= stdev( 15% + 16% + 17% + 18%)
= 1.291%
Hence, the correct option is b.
Answer:
The responses to the given question can be defined as follows:
Explanation:
For point a:
Car arrival time
Each car arrives at an interval of time of 
process time 
The number of vehicles moving in an hour equals 2 per hour.
As 
is greater than 1. The device will not work, resulting in such a revenue loss.
Within 44 minutes, a parking lot would be completely full, with only 1 person being serviced, and then the next empty slot would be completed 64 minutes later.
The system's production capacity is 8.5 per hour [a person entering at 0 will exit at 30]. The person that comes in at 4 will leave at 34. Roughly 50 customers would be supported for an hour.
For point b:
The number of customers would be 
for a 12-hour time frame.
Total cost=
The total number of customers to be served at an expense of 
customers.
Answer:
I would prefer Asset B
Explanation:
A risk averse investor is the one who prefers lower amount of returns with known or specific risks instead of the higher amount of returns with unknown risks. So, from among the various level of risks, the investor will be preferring the alternative with the least interest.
So, in this case,
In Asset A: pay a return of $2,000 and at 20% of time and the $500 at 80% of time.
In Asset B: pay a return of $1,000 and at 50% of time and the $600 at 50% of time.
So, I would prefer, Asset B as it has low return but have a known risk that is of 50 -50.
Answer: After 50 minutes the bell is at a depth of 2000 ft so we can find the average rate by
2000/50 =40 ft per minute.
We ignore the 400 ft in 12 minutes because that is included when we take out the average at 50 minutes and adding it in would be an error of doubly entry.
